This engaging Spanish title tells the story of children who start a business to help people care for their pets. As the business grows, the children use bar, circle, and line graphs as visual representations of their business. These mathematical charts and diagrams help readers understand how to best improve a business. This story not only shows Spanish readers how useful clear graphs can be outside of the classroom, but encourages them to see if they can start their own responsible businesses! Through vibrant images, clear mathematical diagrams, easy-to-read informational text, and text features including a glossary and index, readers will be engaged and encouraged to improve their graphing and STEM skills.
